The Philips PCD3312CT is a versatile single-chip silicon gate CMOS integrated circuit designed for generating DTMF, modem, and musical tones. It is primarily intended for use in telephone sets for tone dialling systems.
Key features include DTMF, modem, and musical tone generation capabilities, along with a stabilized output voltage level that is independent of supply voltage and ambient temperature. The device incorporates on-chip filtering that conforms to CEPT recommendations, ensuring low output distortion. It supports latched inputs for data bus applications and is I2C-bus compatible, allowing for serial data input. The PCD3311C variant also offers selection of parallel or serial (I2C-bus) data input.
Audio output frequencies are generated from an on-chip 3.58 MHz quartz crystal-controlled oscillator. A separate microcontroller is required to control the device. The PCD3312C is suitable for applications requiring reliable and stable audio tone generation.
